OBJECTIVE: Anticoagulation remains the standard of care for line-associated upper extremity deep venous thrombosis (UEDVT). This treatment carries the risk of hemorrhagic complications, possibly more so in surgical patients. Considering the low-risk profile of UEDVT-which is associated with fewer, less severe pulmonary emboli than lower extremity deep venous thrombosis-current UEDVT treatment guidelines may be overly aggressive. The goal of this study was to review outcomes of line-associated UEDVT in critically ill patients and to define the efficacy of current treatment protocols in pulmonary embolism (PE) prevention while avoiding hemorrhagic complications...

BACKGROUND: Our aim was to develop a model of acute right heart failure (ARHF) in the setting of pulmonary hypertension and to characterize acute right ventricular lesions that develop early after hemodynamic restoration. METHODS AND RESULTS: We used a described piglet model of chronic pulmonary hypertension (cPH) induced by pulmonary artery occlusions. We induced ARHF in animals with cPH (ARHF-cPH group, n=9) by volume loading and iterative acute pulmonary embolisms until hemodynamic compromise followed by dobutamine infusion for hemodynamic restoration prior to sacrifice for right ventricular tissue evaluation...

Arterial gas embolism (AGE) can be clinically devastating, and is most often associated with exposure to changes in ambient pressure, medical procedure or congenital malformation. Here we report a case of AGE in a 78-year-old male without these traditional risk factors. Rather, the patient's history included chronic obstructive pulmonary disease, necrotizing pneumonia, bullous disease and coughing. He was safely treated with hyperbaric oxygen (HBO₂) therapy for AGE, with initial clinical improvement, but ultimately died from his underlying condition...

AIMS: Acute thrombosis of hemodialysis (HD) arteriovenous access is an urgent problem for HD patients and is commonly managed by endovascular thrombolysis. Pulmonary embolism (PE) is a recognized complication of HD access thrombosis and thrombolysis but the risk and outcomes are unclear. This study aims to determine the incidence, predictors, and outcomes of PE after endovascular thrombolysis of HD arteriovenous access in patients presenting with acute thrombosis. MATERIALS AND METHODS: A single-center retrospective study was performed for all adult chronic kidney disease patients undergoing arteriovenous access thrombolysis between January 1, 2012, and December 31, 2014...

Venous thromboembolism (VTE) is a common disease (~700 per 100 000) that is associated with significant risk of recurrence, chronic complications, and substantial mortality, with reported death rates of up to 40% at 10 years. The development of novel anticoagulants has revolutionized the treatment of acute VTE, while strategies for prevention and treatment of chronic complications still seek for such a landmark change. Impaired thrombus resolution is the common denominator behind VTE complications, which are postthrombotic syndrome (PTS) and chronic thromboembolic pulmonary hypertension (CTEPH)...

The identification of specific post-thrombotic complications as well as an increased appreciation of the importance of patient-reported outcome measures have triggered an interest in studying health-related quality of life (HRQoL) in patients with a history of venous thromboembolism (VTE). In order to enable a comprehensive assessment of HRQoL in clinical trials it is recommended that both generic and disease-specific questionnaires be used. SF-36 and EQ-5D are the most widely used generic questionnaires in VTE studies, whereas several disease-specific questionnaires have been developed to evaluate HRQoL following deep vein thrombosis (DVT) and in chronic venous disease (CVD)...

Venous thromboembolism (VTE), including pulmonary embolism and deep venous thrombosis, is the third most common cause of cardiovascular death. The management of the acute phase of VTE has already been described in several guidelines. However, the management of the follow-up (FU) of these patients has been poorly defined. This consensus document, created by the Italian cardiologists, wants to clarify this issue using the currently available evidence in VTE. Clinical and instrumental data acquired during the acute phase of the disease are the cornerstone for planning the FU...

BACKGROUND: Amyotrophic lateral sclerosis is a fatal neuromuscular disorder characterized by progressive death of the upper and lower motor neurons in the central nervous system. Patients with this disease die mostly as a result of respiratory failure; however, owing to prolonged survival through assisted ventilation, cardiovascular causes are increasingly responsible for mortality. We report what is to the best of our knowledge the first case of type 2 Brugada syndrome causing ventricular tachyarrhythmia and cardiac arrest in a patient with upper limb onset amyotrophic lateral sclerosis...

Sphingomonas paucimobilis (S. paucimobilis) is a gram negative bacillus. It has existed in soil, drinking water and plants. It has been isolated from distilled water tanks, respirators, and hemodialysis devices at the hospital setting. Patients with chronic disorders or immune suppression may be susceptible to infections with it. This microorganism has also been reported to infect healthy persons. Both nosocomial and community-acquired infections have been reported. So far, a variety of infections have been reported, including sepsis, septic pulmonary embolism, septic arthritis, peritonitis, and endophthalmitis...

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but debilitating and life-threatening complication of acute pulmonary embolism. Circular RNAs (circRNAs), presenting as covalently closed continuous loops, are RNA molecules with covalently joined 3'- and 5'-ends formed by back-splicing events. circRNAs may be significant biological molecules to understand disease mechanisms and to identify biomarkers for disease diagnosis and therapy. The aim of this study was to investigate the potential roles of circRNAs in CTEPH...

Venous malformations have static venous lakes that predispose to spontaneous venous thrombosis within the malformation due to its low-flow static state. Thrombi of varying sizes can then embolize continually into the pulmonary arterial circulation, and occlude and narrow elastic pulmonary arteries causing chronic thromboembolic pulmonary hypertension (CTEPH). Pulmonary thromboendarterectomy (PTE) is potentially curative in CTEPH, but has not been previously reported in the setting of mediastinal and chest wall venous malformations...

The post-Pulmonary Embolism (post-PE) syndrome is being increasingly recognized as a long-term consequence of PE. Its most severe manifestation, chronic thromboembolic pulmonary hypertension (CTEPH), affects a small proportion of PE survivors. However, many more with less severe post-PE syndrome have reduced quality of life and functional capacity. The pathophysiology is incompletely understood, but involves unresolved pulmonary artery thrombi, right ventricular damage, and abnormal gas exchange. Treatment has only been established for CTEPH, and further studies are required to determine how less severe forms of the post-PE syndrome should be treated and if preventive strategies can reduce its incidence...

Both pharmacological and invasive treatment of chronic thromboembolic pulmonary hypertension (CTEPH) is now available in Poland and the awareness of the disease among physicians is growing. Thus, the Polish Cardiac Society's Working Group on Pulmonary Circulation in cooperation with independent experts in this field, have launched the statement on algorithm to guide a CTEPH diagnosis in patients with previous acute pulmonary embolism (APE). In Poland, every year this disease affects about 250 patients. CTEPH should be suspected in individuals after APE with dyspnea, despite at least 3 months period of effective anticoagulation, particularly when specified risk factors are present...

Chronic thromboembolic pulmonary hypertension (CTEPH) is a unique form of pulmonary hypertension arising from fibrotic obliteration of major pulmonary arteries. Pro-thrombotic states, large clot burden and impaired dissolution are believed to contribute to the occurrence and progression of thrombosis after an acute pulmonary embolic event. Recent data utilizing several models have facilitated the understanding of clot resolution. This review summarizes current knowledge on pathophysiological mechanisms of major vessel occlusion in CTEPH...
